Subject: Round to two decimal place

Hi
   I have a variable  say  @price. It is either blank or has a value. If
it is blank I have to show it like  $ 0.00  . So I wrote helper like

@price.blank? ? '$'+'0.00' : '$'+@price.to_s


     But the problem if @price has value 400.00  , after doing
@price.to_s  it changes to 400.0  What I want is exactly  400.00 .And if
I remove to_s above it will throw an error
can't convert BigDecimal into String

    Please help
Thanks
Tom
